Hello
Most of the 9mm reviews that I did were shot with two guns.
A SIG 365 SAS, with a 3.1 inch barrel and a Taurus G3 with a 4 inch barrel.
First I do forensic exam of the ammunition. Next I shoot a group while chronographing with each gun. 10 yards with the SIG and 15 yards with the G3. Chronograph is a Oehler 35P
Then the ammunition is shot out of each gun into a 55 gallon plastic barrel of water. The bullets are then recovered, photographed and then measured for expansion. In cases where the bullet fragments and loses its jacket, a weight is taken with all the recovered material and also a weight taken with just the lead core.
Here is the link to all the photos of the review;
9mm COLT Defense 124gr JHP — Postimages
Data Sheet;
Accuracy and velocity are very acceptable. But as you can see, the bullets did fragment badly in water. I didn't wind up with any Double Tap ammunition to see if the two are similar.
